There’s a ringtone that older people can't hear!
Finally, a solution for every in-class texter! The Mosquito ring tone takes advantage of older people’s inability to hear certain pitches of sound. It emits a tone that is outside the hearing range for most people over the age of 30. What this means is that if you’re a young adult/teenager/baby, you can receive phone calls/texts without your parents/teachers even noticing.
You see it’s a proven medical fact that, as we get older, our ear drums and inner ear become less active, and less able to pick up certain sounds. Young people are able to detect the Mosquito Ring Tone because their ear drums and inner ear are flexible enough to detect such sound vibrations. You can download free Mosquito Ring Tones and test out each one on the Mosquito Ring Tone website.
